Question

Iron is stored in bone marrow as

• A. Hemosiderin
• B. Ferritin
• C. Haematin
• D. None of the above

Answer 1

The correct option is B Ferritin

• Iron is needed to form hemoglobin, part of red blood cells that carry oxygen and remove carbon dioxide (a waste product) from the body. Iron is mostly stored in the body in the hemoglobin.
• About one-third of iron is also stored as ferritin in the bone marrow. Ferritin is a universal intracellular protein that stores iron and releases it in a controlled fashion.
• Hence Iron is stored in bone marrow as Ferritin.
• So, the correct answer is 'Ferritin'.
